How to Update .HK Registrant or Contact Information


If you need to update the information of a .hk domain, the correct process depends on what type of information you want to change.
Some contact information may be updated more easily, such as an email address, phone number, or administrative contact details.
However, changes to the domain holder, registrant name, organization name, or ownership information may require additional verification and should be handled carefully.
This guide explains the difference between a contact update and a registrant information change, what documents may be required, and when you should contact NiceNIC support.

1. What Information Can Be Updated?
Depending on the domain status, account permission, and registry or registrar rules, the following information may be updated:
registrant contact email;
administrative contact email;
technical contact email;
phone number;
address;
administrative contact person;
technical contact person;
organization contact information;
nameserver or DNS settings;
domain holder or registrant information, if allowed and verified.
Not every update follows the same process.
A simple contact update is different from a registrant or ownership change.

2. What Is a Contact Update?
A contact update usually means changing contact details without changing the legal domain holder.
Examples:
  • updating the contact email address;
  • changing the phone number;
  • correcting the mailing address;
  • changing the administrative contact person;
  • updating the technical contact person;
replacing an outdated company contact email with a current role-based email.
Example: The domain holder remains ABC Limited, but the administrative email changes from [email protected] to [email protected].
This is usually considered a contact update, not an ownership change.

3. What Is a Registrant or Ownership Change?
A registrant or ownership change means changing the legal domain holder or the party that owns or controls the domain registration.
Examples:
changing the registrant from one individual to another individual;
changing the registrant from an individual to a company;
changing the registrant from one company to another company;
changing the legal company name;
transferring the domain ownership after a business acquisition;
correcting a registrant name that was entered incorrectly during registration.
These changes may require additional verification documents. Do not treat a registrant or ownership change as a simple contact update.

4. Why Does the Difference Matter?
The difference matters because the domain holder is the party legally associated with the domain registration.
Changing an email address is usually a management update.
Changing the registrant name may affect domain ownership, verification, dispute handling, renewal authority, transfer authority, and account security.
For this reason, registrant-level changes may require stricter review.

5. Can I Update .HK Contact Information Myself?
Some contact information may be updated through your NiceNIC account if the domain is managed under your account and the update function is available.
However, if the update involves the registrant name, organization name, ownership, or document-based eligibility, please contact NiceNIC support first.
If you are not sure whether your request is a simple contact update or a registrant change, contact support before making changes.

6. When Should I Contact NiceNIC Support?
You should contact NiceNIC support if:
  • you need to change the domain holder name;
  • you need to change the registrant organization;
  • the registrant name does not match your document;
  • you need to correct a company name;
  • your company has changed its legal name;
  • the domain ownership needs to be transferred;
  • you are not sure whether the update affects ownership;
  • the domain is under review, suspended, expired, locked, or involved in a dispute;
  • you cannot update the contact information from your account;
  • the WHOIS information appears incorrect or outdated.
For major changes, do not repeatedly edit the contact information before support review. This may create confusion or delay verification.

7. What Information Should I Provide?
When contacting NiceNIC support, please provide:
  • full domain name;
  • NiceNIC account email or username;
  • current registrant name;
  • information you want to change;
  • reason for the update;
  • whether the change is for email, phone, address, organization name, or ownership;
  • supporting document if the change involves registrant name or organization information;
  • any relevant notice, order number, or previous ticket reference.
The clearer your request is, the faster our team can review the correct process.

8. What Documents May Be Required?
Documents may be required if the update involves registrant identity, organization identity, eligibility, or ownership.
Possible documents may include:
  • Hong Kong Business Registration Certificate;
  • company registration certificate;
  • certificate of name change;
  • authorization letter;
  • identity document;
  • proof of Hong Kong residency;
  • organization registration document;
  • non-profit status document;
  • school or institution document;
  • other documents required for the specific .hk category.
The required document depends on the domain category and the nature of the change.

9. What If My Company Name Changed?
If your company name changed, please contact NiceNIC support before updating the registrant information.
You may need to provide a document showing the company name change, such as a certificate of name change or other official company document.
The purpose is to verify that the updated company name is connected to the existing domain holder.

10. What If the Registrant Name Was Entered Incorrectly?
If the registrant name was entered incorrectly during registration, contact NiceNIC support as soon as possible.
Please provide:
  • the domain name;
  • the incorrect registrant name;
  • the correct registrant name;
  • explanation of the error;
  • supporting document showing the correct name.
Do not assume that all registrant name errors can be corrected automatically. Some corrections may require review.

11. Can I Change a .com.hk Registrant to a Different Company?
A .com.hk domain is generally linked to a commercial entity and may require company documents.
Changing the registrant from one company to another may be treated as a registrant or ownership change, not a simple contact update.
Please contact NiceNIC support before making this request.
You may need to provide documents for the current registrant, the new registrant, and the reason for the change.

12. Can I Change an Individual Registrant to a Company?
Changing from an individual registrant to a company may affect ownership and eligibility.
This type of change should be reviewed by support before processing.
Depending on the domain category, company documents or authorization documents may be required.

13. Can I Change the Contact Email If I Lost Access to the Old Email?
If you lost access to the current contact email, contact NiceNIC support.
For account security reasons, we may need to verify your identity or account control before changing the email.
Please provide:
  • domain name;
  • NiceNIC account information;
  • old contact email;
  • new contact email;
  • reason for the change;
  • verification documents if requested.
Do not submit a new account or duplicate order for the same domain before the case is reviewed.

14. What If the Domain Is Expired, Locked, or Under Review?
If the domain is expired, locked, pending review, under dispute, or under compliance review, some update functions may be limited.
Please contact NiceNIC support before attempting to update information.
The available options may depend on:
  • domain status;
  • renewal status;
  • registry rules;
  • account verification;
  • document review;
  • dispute or compliance situation.

15. Will WHOIS Update Immediately After I Change Information?
Not always. After a contact or registrant information update, WHOIS display may take some time to refresh.
Also, not all information may be publicly displayed due to registry policy or privacy-related rules.
If you have updated your information but the WHOIS record has not changed immediately, please wait and check again later. If the issue continues, contact NiceNIC support.

16. What Should I Avoid?
To reduce delay or risk, avoid the following:
  • submitting false contact information;
  • using an unreachable email address;
  • using another companyos document;
  • changing registrant name without support review;
  • changing company name to a brand name that does not match documents;
  • using personal information for a company-category domain when company documents are required;
  • using company information for an individual-category domain when individual proof is required;
  • ignoring document review notices;
  • repeatedly changing information before verification is completed.
Accurate and consistent information helps protect your domain ownership and management rights.
